Get the 32bit Professional version unless you want to re-purchase all of your Windows apps. I don't think that Windows allows you to use 32 bit apps in the 64bit version.

Eh, no. XP 64 was bad, but Vista and 7 are not. But he's probably not going to be allocating more than 4GB of RAM to it, so no point in going 64.
